[draft] Update the User info in the Presence Channel call

[MarGul]

This PR is not fully complete yet because it lacks the essentials tests. I'm having a little bit trouble of how I should test this feature but wanted to create the PR first to see that it will be accepted before I spend too much time on it.

Basically what I've done here is to create an API route to update the current user_info in presence channels. This is a highly sought after feature in Pusher but they haven't implemented it yet. You can see it here: https://stackoverflow.com/questions/24874279/how-to-change-member-info-in-pusher and https://stackoverflow.com/questions/29207414/save-to-user-info-on-pusher-presence-channels.

Personally I need this because I'm storing data here that I need to keep in sync. The problem I have is if UserA logs in and sets his user_info to on_call => false and then when UserB logs in he will get the on_call => false data for UserA. If now UserA answers a call I send out a client event setting this data (on client side) to on_call => true for UserA. This all works good but if UserB now reloads his page he will get the initial user_info that was set when UserA authenticated which would be on_call => false.

By having an API to update the user_info state this solves my problem. When UserA accepts a call I update the state on my websocket server meaning that UserB (and every other User's joining) will now have an updated info on UserA where on_call => true.

Hope you would accept this Pull Request and if you do, maybe give me some pointer of how to write a good test for this functionality. Maybe I need unit test to see that the updateUserInfo function works properly or do it by a Controller test like I've started.

@MarGul I know this is a draft PR, but we'll discuss it after #140 gets applied.

Thanks @rennokki for jumping on as a maintainer. Would be awesome to get this PR in.

I have marked it as postponed until the 2.x comes to avoid conflicts pretty much under the hood: #447

Thanks. Do you have any perception of time until we can have a look at this PR and maybe get it merged?
